2019-01-14nbd: Merge nbd_export_bitmap into nbd_export_newEric Blake
We only have one caller that wants to export a bitmap name, which it does right after creation of the export. But there is still a brief window of time where an NBD client could see the export but not the dirty bitmap, which a robust client would have to interpret as meaning the entire image should be treated as dirty. Better is to eliminate the window entirely, by inlining nbd_export_bitmap() into nbd_export_new(), and refusing to create the bitmap in the first place if the requested bitmap can't be located. We also no longer need logic for setting a different bitmap name compared to the bitmap being exported.

2019-01-14nbd: Merge nbd_export_set_name into nbd_export_newEric Blake
The existing NBD code had a weird split where nbd_export_new() created an export but did not add it to the list of exported names until a later nbd_export_set_name() came along and grabbed a second reference on the object; later, the first call to nbd_export_close() drops the second reference while removing the export from the list. This is in part because the QAPI NbdServerRemoveNode enum documents the possibility of adding a mode where we could do a soft disconnect: preventing new clients, but waiting for existing clients to gracefully quit, based on the mode used when calling nbd_export_close(). But in spite of all that, note that we never change the name of an NBD export while it is exposed, which means it is easier to just inline the process of setting the name as part of creating the export. Inline the contents of nbd_export_set_name() and nbd_export_set_description() into the two points in an export lifecycle where they matter, then adjust both callers to pass the name up front. Note that for creation, all callers pass a non-NULL name, (passing NULL at creation was for old style servers, but we removed support for that in commit 7f7dfe2a), so we can add an assert and do things unconditionally; but for cleanup, because of the dual nature of nbd_export_close(), we still have to be careful to avoid use-after-free. Along the way, add a comment reminding ourselves of the potential of adding a middle mode disconnect.

2019-01-14xen: automatically create XenBlockDevice-sPaul Durrant
This patch adds create and destroy function for XenBlockDevice-s so that they can be created automatically when the Xen toolstack instantiates a new PV backend via xenstore. When the XenBlockDevice is created this way it is also necessary to create a 'drive' which matches the configuration that the Xen toolstack has written into xenstore. This is done by formulating the parameters necessary for each 'blockdev' layer of the drive and then using qmp_blockdev_add() to create the layers. Also, for compatibility with the legacy 'xen_disk' implementation, an iothread is automatically created for the new XenBlockDevice. This, like the driver layers, will be destroyed after the XenBlockDevice is unrealized. The legacy backend scan for 'qdisk' is removed by this patch, which makes the 'xen_disk' code is redundant. The code will be removed by a subsequent patch.

2019-01-14xen: add a mechanism to automatically create XenDevice-s...Paul Durrant
...that maintains compatibility with existing Xen toolstacks. Xen toolstacks instantiate PV backends by simply writing information into xenstore and expecting a backend implementation to be watching for this. This patch adds a new 'xen-backend' module to allow individual XenDevice implementations to register create and destroy functions. The creator will be called when a tool-stack instantiates a new backend in this way, and the destructor will then be called after the resulting XenDevice object is unrealized. To support this it is also necessary to add new watchers into the XenBus implementation to handle enumeration of new backends and also destruction of XenDevice-s when the toolstack sets the backend 'online' key to 0. NOTE: This patch only adds the framework. A subsequent patch will add a creator function for xen-block devices.

2019-01-14xen: add xenstore watcher infrastructurePaul Durrant
A Xen PV frontend communicates its state to the PV backend by writing to the 'state' key in the frontend area in xenstore. It is therefore necessary for a XenDevice implementation to be notified whenever the value of this key changes. This patch adds code to do this as follows: - an 'fd handler' is registered on the libxenstore handle which will be triggered whenever a 'watch' event occurs - primitives are added to xen-bus-helper to add or remove watch events - a list of Notifier objects is added to XenBus to provide a mechanism to call the appropriate 'watch handler' when its associated event occurs The xen-block implementation is extended with a 'frontend_changed' method, which calls as-yet stub 'connect' and 'disconnect' functions when the relevant frontend state transitions occur. A subsequent patch will supply a full implementation for these functions.

2019-01-14xen: create xenstore areas for XenDevice-sPaul Durrant
This patch adds a new source module, xen-bus-helper.c, which builds on basic libxenstore primitives to provide functions to create (setting permissions appropriately) and destroy xenstore areas, and functions to 'printf' and 'scanf' nodes therein. The main xen-bus code then uses these primitives [1] to initialize and destroy the frontend and backend areas for a XenDevice during realize and unrealize respectively. The 'xen-block' implementation is extended with a 'get_name' method that returns the VBD number. This number is required to 'name' the xenstore areas. NOTE: An exit handler is also added to make sure the xenstore areas are cleaned up if QEMU terminates without devices being unrealized. [1] The 'scanf' functions are actually not yet needed, but they will be needed by code delivered in subsequent patches.

2019-01-14xen: introduce 'xen-block', 'xen-disk' and 'xen-cdrom'Paul Durrant
This patch adds new XenDevice-s: 'xen-disk' and 'xen-cdrom', both derived from a common 'xen-block' parent type. These will eventually replace the 'xen_disk' (note the underscore rather than hyphen) legacy PV backend but it is illustrative to build up the implementation incrementally, along with the XenBus/XenDevice framework. Subsequent patches will therefore add to these devices' implementation as new features are added to the framework. After this patch has been applied it is possible to instantiate new 'xen-disk' or 'xen-cdrom' devices with a single 'vdev' parameter, which accepts values adhering to the Xen VBD naming scheme [1]. For example, a command-line instantiation of a xen-disk can be done with an argument similar to the following: -device xen-disk,vdev=hda The implementation of the vdev parameter formulates the appropriate VBD number for use in the PV protocol.

2019-01-11qemu/queue.h: simplify reverse access to QTAILQPaolo Bonzini

2019-01-11qemu/queue.h: reimplement QTAILQ without pointer-to-pointersPaolo Bonzini
QTAILQ is a doubly linked list, with a pointer-to-pointer to the last element from the head, and the previous element from each node. But if you squint enough, QTAILQ becomes a combination of a singly-linked forwards list, and another singly-linked list which goes backwards and is circular. This is the idea that lets QTAILQ implement reverse iteration: only, because the backwards list points inside the node, accessing the previous element needs to go two steps back and one forwards. What this patch does is implement it in these terms, without actually changing the in-memory layout at all. The coexistence of the two lists is realized by making QTAILQ_HEAD and QTAILQ_ENTRY unions of the forwards pointer and a generic QTailQLink node. Thq QTailQLink can walk the list in both directions; the union is needed so that the forwards pointer can have the correct type, as a sort of poor man's template. While there are other ways to get the same layout without a union, this one has the advantage of simpler operation in the debugger, because the fields tqh_first and tqe_next still exist as before the patch. Those fields are also used by scripts/qemugdb/mtree.py, so it's a good idea to preserve them. The advantage of the new representation is that the two-back-one-forward dance done by backwards accesses can be done all while operating on QTailQLinks. No casting to the head struct is needed anymore because, even though the QTailQLink's forward pointer is a void *, we can use typeof to recover the correct type. This patch only changes the implementation, not the interface. The next patch will remove the head struct name from the backwards visit macros. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2019-01-11qemu/queue.h: typedef QTAILQ headsPaolo Bonzini
This will be needed when we change the QTAILQ head and elem structs to unions. However, it is also consistent with the usage elsewhere in QEMU for other list head structs (see for example FsMountList). Note that most QTAILQs only need their name in order to do backwards walks. Those do not break with the struct->union change, and anyway the change will also remove the need to name heads when doing backwards walks, so those are not touched here.

2019-01-11qemu/queue.h: leave head structs anonymous unless necessaryPaolo Bonzini
Most list head structs need not be given a name. In most cases the name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV or reverse iteration, but this does not apply to lists of other kinds, and even for QTAILQ in practice this is only rarely needed. In addition, we will soon reimplement those macros completely so that they do not need a name for the head struct. So clean up everything, not giving a name except in the rare case where it is necessary. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2019-01-11scsi: esp: Defer command completion until previous interrupts have been handledGuenter Roeck
The guest OS reads RSTAT, RSEQ, and RINTR, and expects those registers to reflect a consistent state. However, it is possible that the registers can change after RSTAT was read, but before RINTR is read, when esp_command_complete() is called. Guest OS qemu -------- ---- [handle interrupt] Read RSTAT esp_command_complete() RSTAT = STAT_ST esp_dma_done() RSTAT |= STAT_TC RSEQ = 0 RINTR = INTR_BS Read RSEQ Read RINTR RINTR = 0 RSTAT &= ~STAT_TC RSEQ = SEQ_CD The guest OS would then try to handle INTR_BS combined with an old value of RSTAT. This sometimes resulted in lost events, spurious interrupts, guest OS confusion, and stalled SCSI operations. A typical guest error log (observed with various versions of Linux) looks as follows. scsi host1: Spurious irq, sreg=13. ... scsi host1: Aborting command [84531f10:2a] scsi host1: Current command [f882eea8:35] scsi host1: Queued command [84531f10:2a] scsi host1: Active command [f882eea8:35] scsi host1: Dumping command log scsi host1: ent[15] CMD val[44] sreg[90] seqreg[00] sreg2[00] ireg[20] ss[00] event[0c] scsi host1: ent[16] CMD val[01] sreg[90] seqreg[00] sreg2[00] ireg[20] ss[02] event[0c] scsi host1: ent[17] CMD val[43] sreg[90] seqreg[00] sreg2[00] ireg[20] ss[02] event[0c] scsi host1: ent[18] EVENT val[0d] sreg[92] seqreg[04] sreg2[00] ireg[18] ss[00] event[0c] ...

2019-01-11accel: Improve selection of the default acceleratorThomas Huth
When compiling with "--disable-tcg", we currently still use "tcg" as default accelerator. "kvm" should be used in this case instead. Also, some downstream distros provide QEMU binaries which have "kvm" in their names (e.g. "qemu-kvm" on RHEL or "kvm" on Ubuntu) that use KVM by default - and some users might want to do something similar with upstream binaries, too. Accomodate them by using "kvm:tcg" as default when we detect such a binary name.

2019-01-10configure: bump spice-server required version to 0.12.5Marc-André Lureau
Looking at chardev/spice.c code, I realize compilation was broken for a while with spice-server < 0.12.3. Let's bump required version to 0.12.5, released May 19 2014, instead of adding more #ifdef. (this patch combines changes from an early version and some of Frediano "[PATCH 2/2] spice: Bump required spice-server version to 0.12.6") According to repology, all the distros that are build target platforms for QEMU include it: RHEL-7: 0.14.0 Debian (Stretch): 0.12.8 Debian (Jessie): 0.12.5 FreeBSD (ports): 0.14.0 OpenSUSE Leap 15: 0.14.0 Ubuntu (Xenial): 0.12.6 Note that a previous version of this patch was bumping version to 0.12.6. Unfortunately, Debian Jessie (oldstable) is stuck with spice server 0.12.5, and QEMU should keep building until after 2y of current stable (Stretch), which will be around June 17th 2019. Qemu 4.1 should thus be free of bumping to spice-server 0.12.6 during 4.1 development cycle. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Daniel P.

The machine starts with the legacy mode and a new interrupt mode can then be negotiated by the CAS process. In this case, the new mode is activated after a reset to take into account the required changes in the machine. These impact the device tree layout, the interrupt presenter object and the exposed MMIO regions in the case of XIVE.
